WEATHER STOP.

Application filed October 24, 1927.

The invention relates to improvements in weather-stops of the type d:igned for mounting in a groove in the lower end of a door. or otherpivoted closure, provision being made for depressing the stop when thedoor or the like is closed and for retracting it when the closure isopened.

F or purposes of description and convenience, the word door will behereinafter used in a sense comprehending any other form of pivotedclosure than an actual door, for instance, a casement window.

@ne object of the invention is to provide a new and improved casingconstruction for the depressible weather strip, provided with novelmeans for attachin it to the door.

A further aim to proviue unique operating means for automaticallydepressing the spring-raised weather-strip unen the door is closed.

Yet another aim is to provide a unique thrust device for bringing thestrip-depressing means into play when the door is closed, said thrustdevice being adjustable to permitproper initial setting of the deviceand to compensa-ite for wear of the weather strip by contact with thesill.

lVith the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawing.

Fig. 1 is a side elevation partly in section showing the inventionapplied to a door.

Fig. 2 is a longitudinal. sectional view.

Figs. 8, 4 and 5 are horizontal sectional views on the correspondinglynumbered lines of Fig. 2.

Figs. 6 and 7 are vertical transverse sec tional views as indicated bylines 66 and 7-7 of Fig. 2.

In the drawing above briefly described, the numerals 8 denote twohorizontally elongated sheet metal plates which are disposed in spacedvertical planes, the upper edges of said plates being provided withoverlapped flanges 9 secured together by belts or the like 10, while theends oi said plates are provided with inwardly stamped lugs 11 which arealso disposed in overlapping relation. The innermost of these lugs havenuts 12 soldered thereto, and said lugs are apertured in line with theopenings of the nuts. In this connection, it may also be stated that thenuts 13 of the bolts are preferably soldered to the lowermost of theflanges 9.

Serial No 228,400.

Two vertically disposed end plates 1 1 are provided for the casingformed by the connected plates 8, said plates being length to projectabove the and being of a width. to project laterally in oppositedirections therefrom. These plates are provided with upper openings 15to receive attaching fasteners 16 for securing them to the oppositeedges of a door, saio plates being inset in said edges, as shown. Theplates 14 are also formed with lower openings 17 horizontallv alinedwith the nuts 12 and the openings of the lugs or cars 11. Screws 18 passthrough the openings 1?, through the open ings of the lugs or ears 1.1and are threaded into the nuts 12. Thus, the end plates 14 areeffectively connected with the casing for sup porting the latter in agroove 19 formed in the lower end of the door 20, and it the device heapplied to a door of somewhat excess width, the screws 18 will permitthe necessarv outward sparing or the plates 14, from the ends of thecasing.

91 metal-backed weather strip 21 of felt or other desired material, isslidably mounted in the casing and its back 22 is suitably connected atwith a spring 24, the latter being securely mounted in the casing, wit-hthe aid of pins 25 and 26 whose ends are received in openings in the.plates 8.. said spring having an eye 27 through which the pin 25 pas. s.while the pin 26 merely underlies said spring: This spring acts in a.manner to lift the weather strip when such lifting is permitted, but aslong as the door stays closed. said strip is held in a depressedposition in contact with the door sill, by means hereinafter described.

A bell. crank 28 is fulcrumed in the casing and is provided with arelatively long hori zontal arm 29 and a comparatively short verticalarm 30, the former being suitably related with a strip 21 while the arm30 projects upwardly through a slot 32 formed in the top of the casingnear one end of the latter, said casing top preferably having upstandinglongitudinal flanges 83 along the edges of this slot.

Between this slot and the adjacent end of the casing, the casing top isprovided with apair of horizontally alined plunger guides 34, and theadjacent end plate 15 is formed with an opening 85 alined with saidguides. A plunger 36 is slidable in the guides 34 and is formed with areduced end 37 passing outwardly through the opening 35, while the innerend of this plunger is directed upwardti l ly and inwardly at 38,extends through the slot 32 and contacts with the bell crank arm 80.Thus, inward pushing of the plunger 3'7, causes rocking of the bellcrank 28 to depress the weather strip 29 against the action of thespring 24, but as soon as outward movement of said plunger is permitted,the spring will again raise the weather strip.

A novel thrust device is carried by one side of the door frame 39 forinwardly forcing the plunger 36 when the deer is closed. "his thrustdevice embodies a wood screw 40 having an enlarged head provided with anaxial socket 41. A set screw 42 is threaded adjustably into this socketand a locl: nut 4.3 is provided for said set screw. The head of thescrew 42 strikes the reduced end 37 of the plunger 36 to effect inwardsliding of the latter when the door is closed but upon opening of saiddoor, the plunger is released to permit raising of the strip 21 underthe influence of the spring 24.

WVhen initially applying the device, the screw 42 may be adjusted to theproper extent and then-locked by the nut 43, insuring that upon closingof the door, the strip 21 shal be depressed into tight contact with thedoor sill. Later on, if the lower edge of the strip 21 becomes so wornthat it does not tightly contact with the sill, the screw l2 may beadjused outwardly from the screw 40, cansing it to inwardly force theplunger 36 to a greater extent, thus eompei'isating for the wear.

As excellent results are obtainable from the details disclosed, they arepreferably followed. However, within the scope of the in vention asclaimed, variations may be made.

I claim 1. In a weather stop, a horizontally elongated open-ended casingfor reception in a groove in the lower end of a door, said casing havingmembers in its open ends formed with openings, a pair of vertical endplates for said casing of a length to project upwardly therefrom, saidplates having lower openings alined with the aforesaid openings andupper openings above the casing to receive fasteners for securing theplates to the door edges, and threaded fasteners passing through saidlower openings and the first named openings, said. threaded fastenerspermitting different spacing of the end plates from the casing tocompensate for variance in door widths.

2. In a weather stop, two horizontally elongated plates disposed inspaced vertical planes, said plates having overlapping longitudinalflanges at their upper edges secured together, and overlapping ears attheir ends formed with horizontally alined openings, end plates for thecasing of a length to project upwardly from said casing, said end plateshaving lower openings alined with the first named openings, and upperopenings above the casing to receive fasteners for securing the platesto the edges of the door, and tl 'eaded fasteners passing through thelower openings and through said first named openings.

A weather stop comprising a horizontally elongated casing for mountingin a groove in the lower end of a door, the top of said casing beingprovided near one end with a slot and with plunger-guiding means betweensaid slot and end, a spring-raised weather strip in the casing, a bellcrank fulcruined in said casing and having a horizontal arni engagedwith said strip and a V61' tical arm projecting upwardly through saidslot, and an operating plunger for said bell crank, said plunger beingslidably mounted in said plunger-guiding means and having an upwardlyand inwardly directed inner end which passes through said slot and abutssaid vertical arm of the bell crank.

In testimony whereof I have hereunto affixed my signature.
